Stalking Ex!!!

Glow Family I need some suggestions , my ex fiancé , let’s make a long story short we both lived in two different states he came to visit me one time for a holiday and we only dated long distance for 4 months , at that time I was 16 and he was 24 he proposed I was “ in love ” bit confused mostly , I always dreamed of being married starting a family and just continuing my life by following my dreams . Anyways he left back to his home town and I stayed in my home town I was waiting to graduate so I can move with him , things were not ok but I was blinded by love . I lived in a home where fighting was always what we saw there were no calm nights or “love” and I just didn’t want to hold someone back because I didn’t feel any love so I broke it off , moving forward to my life I got married to my wonderful loving husband in 2015 and now I have my ex fiancé stalking me continuously making fake social media accounts and just trying to follow my page thinking I am not on alert to block him . I have about 15 pages blocked from him , it has become worst and worst . I feel like I might be the one going crazy over reacting but no matter how many times I report him on social media it continues and continues . I used to live off social media to keep a low profile but I didn’t want to continue living that way so got rid of the fear and just made social media accounts for my family and friends but this is getting out of hand he is doing everything he can to make more accounts and try to follow me and I block him before I even let him message me to contact me . Not sure what else to do ..
